Take the pallet off and you will find holes in the hair pin filled with lead plugs. Remove one or more and voila you have your desired spec. Cant remember how much each weight weighs but it is quite a bit.My TC97 is here, so I am officially in the club now. I bought it used from tt member. Here is the trouble: I put it on scale and it is strung, with leather grip 352g. I play with usually with up to 320g strung. I think this will be simply too much for me (I haven't played it yet though). So How to get it closer to my spec? Or rather: what kind of weight I can expect to find in hairpin or where? I haven't found any video tutorial how to play with Angell racquets and never done such a modification myself. Any advice mates?
